Every cell in your body carries the same genetic instructions, and yet cells don't accidentally turn into bone inside your heart, and teeth don't grow in your brain. This is thanks to systems of precise control over the expression ...

When egg and sperm combine, the new embryo bustles with activity. Its cells multiply so rapidly they largely ignore their DNA, other than to copy it and to read just a few essential genes. The embryonic cells mainly rely ...

The first step in gene expression is the exact copying of a segment of DNA by the enzyme known as RNA polymerase II, or pol II, into a mirror image RNA. Scientists recognize that pol II does not transcribe RNA via a smooth ...
